Specific embodiment

Present invention relates in general to a kind of for the dynamic stitch density that changes to optimize the method for quilter output and to be System.Embodiments of the invention include, and determine which part (if present) of quilting pattern meets and substitute pin for sewing The threshold requirement of pin density, this replacement stitch density is different from the standard stitch density being initially applied to sewing pattern.As herein Used in, " requirement " is not construed as strict or absolute restriction, and only refers only to or define that the present invention exists The one or more preferred or optimum measured value (such as threshold angle) using for realizing its purpose herein.In each reality Apply in example, for any number of applicable threshold value described below, " requirement " can be the correlative measurement determining in pattern The scope of value (such as inch, the number of degrees), can be determined in advance, can be limited by user, can be arranged by machine or manufacture Constraints determines.In certain embodiments, the method dynamically changing the stitch density of pattern sewed by quilter is included, Determine whether the part of the element-specific of pattern meets for the dynamic threshold value changing stitch density (that is, applying " hydridization stitch ") Require.

Based on the analysis to some embodiments of the present invention, dynamically change the stitch density of the specific part of sewing pattern, Thus optimize the yardage output of quilter, sewing velocity is maintained at constant SPM and/or RPM speed simultaneously.So, exist In the case of not changing sewing velocity, embodiments of the invention can be used for dynamically being used in sewing/quilting figuratum The yardage of sewing machine and/or quilter maximizes.Based on analysis sewing/quilting pattern and in the element-specific of pattern automatically Apply variable stitch density, with respect to using the sewing thread amount needed for constant higher stitch density sewing identical patterns Speech, it is possible to reduce sewing thread amount (the line code number consuming).In addition, in an embodiment of the present invention, sewing can be maintained reliable Property, optimize yardage output simultaneously.In one embodiment, sewing reliability also refers to during sewing or quilting pattern The not ability of bouncing pilotage and/or dropped stitch.

In other embodiments, during sewing, the dynamic stitch density that changes provides each element (example to sewing pattern Element as quilting pattern) real-time analysis.Therefore, need lower stitch density for comparing other sewing regions Pattern element, the analysis of the present invention can provide the pattern automatically adjusting special stitch density.Similarly, dynamic during sewing The embodiments of the invention changing stitch density provide the special stitch density of pattern for some elements, with respect to the stitch of surrounding For the relatively low element of density, these elements need higher stitch definition and accordingly higher stitch density.In the present invention Other embodiments in, can to whole quilting pattern application standard stitch density, and application the present invention analysis after, The one or more of quilting pattern partly can be identified as being suitable for being stitched with the stitch density lower than standard stitch density Thread.Therefore, these lower stitch density adjust and can lead to save line code number (for example, when making sewing pattern or part thereof Shi Keneng needs or using less line code number).Other embodiments of the invention include, for standard stitch density is usually used The pattern element of sewing is analyzed, to determine whether to meet for the identified part change stitch density to pattern element Threshold requirement.

Embodiments of the invention include a kind of for specifying variable stitch density in multiple elements of specific pattern Method and system.In one exemplary embodiment of the present invention, there is provided one kind is for automatically referring to the first pattern element Fixed first stitch density and the method that the second stitch density is specified to the second pattern element.First stitch density can be than the second pin Pin density includes less stitch quantity on per inch.Therefore, the present invention can be used for automatically identifying the spy of sewing pattern Determine element, these elements are determined to be needs less stitch definition, and is thus suitable for using the periphery than pattern Lower stitch density is divided to be sewed.So, the specific part of sewing pattern can be identified as being adapted for use with " hydridization pin Pin " (that is, the stitch density lower than the remainder of quilting pattern) is sewed.

Turning now to the exemplary embodiment of in figure, Fig. 1 shows showing using stitch density 12 sewing consistent all the time The embodiment of example property pattern 10.As shown in figure 1, exemplary patterns can include multiple patterns of the method according to the invention identification Element.As used below, element generally refer to can to differentiate with other side can the setting of visual identity Meter aspect.For example, the design aspect of such as straight line can visually be differentiated with curve, and right angle (is for example made up of sewing thread Acute angle turn turning shape) can visually with obtuse angle (for example by the sewing thread structure of two line segments having more than an angle of 90 degrees degree Become turns turning shape, and the summit constituting with respect to this two line segments measures this angle) differentiate.So, in these embodiments, First element 14, second element 16, third element 18, fourth element 20 and The Fifth Element 22 can be identified as quilting pattern 10 Different piece, need during sewing analysis which kind of stitch density is applied to each pattern element.For example, this analysis can be used In determining whether possible application " hydridization stitch " (that is, the stitch density of change).In other words, each of quilting pattern can be analyzed Element, to determine when the different pattern element in sewing pattern 10, if the stitch density being transformed into change (is for example adjusted to The stitch density more higher or lower than standard stitch density).

With reference now to Fig. 2, exemplary quilting pattern 24 describes a kind of change stitch density dynamic during sewing Method.In certain embodiments, the dynamic stitch density that changes is included between more than one stitch density (for example low, middle And high stitch density between；Or in standard and the stitch density of change between) automatically change, and manual identification should be to it Application or the specific pattern element using specific stitch density.In the figure 2 example, the element of the change based on pattern 24, makes With variable stitch density sewing pattern 24.So, the first stitch density 26 is used for sewing the first element 32, third element 36 and The Fifth Element 40, and the second stitch density 28 and 30 is used for sew second element 34 and fourth element 38.In an embodiment, second Stitch density 28 and 30 is identical stitch density, is applied to the similar element of pattern 24.For example, for quilting pattern 24 Straight sections, such as Part I 32, Part III 36 and Part V 40, embodiments of the invention can determine with the first pin Pin density 26 this pattern of sewing.In another embodiment, the bending for the specific part of quilting pattern 24 and/or curved portions Section, such as Part II 34 and Part IV 38, embodiments of the invention can determine with the second stitch density 28 and/or 30 seam Thread this pattern.So, for the straight sections of pattern 24, can be to the needs of pattern 24 less stitch definition (such as straight line) The lower change of certain applications stitch density (that is, " hydridization stitch ").It is likewise possible to the remainder to pattern 24 (including exemplary Part II 34 and Part IV 38) higher stitch density of application is for example higher than the stitch density changing Standard stitch density.

Turning now to Fig. 3, exemplary pattern 42 includes the multiple different units for sewing pattern (such as quilting pattern) The variable stitch density of element.The embodiment of pattern 42 is included with the first element 54 of the first density 44 sewing, with the second density 46 sewing second elements 56, with triple density 48 sewing third element 58, with the 4th density 50 sewing fourth element 60, With the The Fifth Element 62 sewed with the 5th density 52.In an embodiment it may be determined that using variable stitch density 44,46,48, Each of 50 and 52 sewing first, second, third, fourth and fifth pattern elements 54,56,58,60 and 62.Real at some Apply in example, the element (such as 54,56,58,60 and 62) to pattern 42 carries out Threshold Analysis, to identify and/or to determine whether to Using one or more elements (such as 54,56,58,60 and 62) of standard stitch density sewing pattern 42, or whether to use The stitch density one or more elements of sewing (such as 54,56,58,60 and 62) changing.In one embodiment, to pattern 42 Element (such as 54,56,58,60 and 62) carry out stitch density Threshold Analysis determine so as to each element (such as 54,56, 58th, 60 and 62) stitch density determining does not damage sewing machine performance, the quality of final products or productivity ratio.

In other embodiments, variable stitch density 44,46,48,50 and 52 can be different from each other, and can be according to Low, middle or high stitch density classification.For example, stitch density 44 can include the stitch density bigger than stitch density 46.In addition, Stitch density 48 can be middle stitch density so that it is the stitch density lower than stitch density 46, but be closeer than stitch Spend 44 high stitch density.In another embodiment, the method according to the invention, variable stitch density 44,46,48,50 and 52 can be the stitch density increasing little by little and/or step by step or reducing.When changing between different stitch density, this Increase kind progressively or reduce and can allow each variable stitch density close to the pin specified for neighbouring and/or adjacent element Pin density (that is, progressively reaches adjacent stitches density).For example, it is that variable stitch density 44 that element 54 is specified can be with unit Element 54 and 56 between the reduction (for example, persistently sewing to element 56 from element 54 with sewing head) of sewing distance and progressively increase Plus its stitch density.So, in an embodiment of the present invention, the stitch density of a part of element 54 can " oblique ascension " arrive step by step The stitch density specified for element 56.In this example, for a part of element 54 of the starting point near element 56, variable The stitch density of stitch density 44 can increase little by little and/or step by step.In alternative embodiments, be pattern element assignment Stitch density can " oblique deascension ", to include the middle stitch density of the first element portions for neighbouring second element, wherein This second element has the stitch density less than the first element.

In certain embodiments, according to the Threshold Analysis for each element in pattern, each element can be specified multiple Stitch density (and each corresponding element of subsequently sewing).For example, it is possible to the length of analysis straight line, the curvature of arc section, element Angle with regard to axis and/or the relation of an element and another element.In certain embodiments, additional factor is acceptable Including for produce and one or more technical elements assessment, for example possible pin deviation, the machine type being used are (for example Needle ring (needle and looper) is with respect to needlework axle (needle and bobbin) sewing system) and sewed, sew with long stitches The feature of the material of seam, embroidery and/or lock seaming.In an embodiment of the present invention, it is possible to use one or more be used for specify and/ Or the algorithm of the change of regulation stitch density, to optimize accuracy and efficiency, and so that yardage is maximized, ensure not damage simultaneously Sewing reliability (for example preventing bouncing pilotage, poly- line or kinking, broken string).So, in certain embodiments, based on Threshold Analysis and/ Or other analysis, specific element can be identified as needing specific first seam density.For example, Threshold Analysis determine permissible Show, the first seam density of element-specific can meet one or more threshold values, this will enable element-specific with second Seam density is sewed, and thus optimizes one or more of accuracy, efficiency, sewing yardage, sewing reliability etc..

Below with reference to Fig. 4, using variable stitch density along axis 114 sewing pattern 64.In an embodiment, using can The stitch density sewing pattern 64 becoming refers to, sewing pattern 64 is so that at least a portion of at least one element of this pattern 64 Sewed with the first stitch density, at least a portion of at least one element of this pattern 64 is sewed with the second stitch density.For example, One element of pattern 64 can include straight sections, and the Part I of this straight sections is sewed with the first stitch density, and this is straight The Part II of line section is sewed with the second stitch density.In some embodiments of the invention, straight sections can include one Individual or some.Similarly, an element of pattern 64 can include arc section (the bending element of such as pattern), this arc The Part I of shape section is sewed with the first stitch density, and the Part II of this arc section is sewed with the second stitch density.This Sample, which of each pattern element embodiments of the invention be determined for partly will be with the first stitch density (such as standard pin Pin density) sewing, which of each pattern element partly will be sewed with the second stitch density (stitch density of such as change).At it In its embodiment, the stitch density of any number of change can be applied to the different piece of any number of pattern element, Such as the 3rd stitch density is used for a part at least one element of sewing pattern 64.In an embodiment, can be according to this One of multiple stitch density of multiple element assignments of invention identification, with using variable stitch density, with constant sewing Speed is sewed.

In the fig. 4 embodiment, pattern 64 shows sewing pattern 66, and it includes multiple elements, such as first straight line portion Section the 68, first arc section 70, second straight line section 72, the second arc section 74 and the 3rd straight sections 76.The present invention's In embodiment, based on the determination that whether each several part of each element is met with one or more threshold requirement, it is sewing pattern 66 Each section specifies the stitch density for sewing.As shown in the embodiment depicted in fig. 4, during sewing along axis 114, according to this Bright method dynamically changes stitch density.In certain embodiments, axis 114 can be x-axis, and wherein, x-axis have corresponded to Become the bracket axis of the sewing device of sewing pattern (and/or being ready to complete at least a portion sewing pattern).Alternatively, another In embodiment, axis 114 can be y-axis, and wherein y-axis correspond to and complete sewing pattern and (and/or be ready to complete at least one Point sewing pattern) sewing device charging axis.In certain embodiments, the orientation of axis 114 is corresponding to sewing technology One or more technical elements (type for example to the sew related machine of this sewing pattern or device) determination.In Fig. 4 Embodiment in, when for sewing material advance along axis 114 when, with constant speed, sewing pattern 66 can be sewed To on material, and on whole sewing pattern 66, there is variable stitch density.

In one embodiment of the invention, first straight line section 68 is determined meeting for referring to for first straight line section 68 The threshold requirement of the fixed stitch density 80 changing.In an embodiment, first straight line section 68 meets threshold length and with respect to axle The threshold angle of line 114, and therefore it is designated the stitch density 80 (i.e. " hydridization stitch " density) to change.Implement other Example in, based on the analysis of the one or more parts to the first arc section 70, determine the first arc section 70 be unsatisfactory for for Specify the threshold requirement of the stitch density 80 changing, and therefore sewed with standard stitch density 78.In an embodiment, same Sample determines that second straight line section 72 and the 3rd straight sections 76 meet the threshold requirement of the stitch density 80 for specifying change, and Threshold requirement that threeth arc section 74 be unsatisfactory for stitch density 80 for specify change is similarly determined, and is therefore referred to Determine with standard stitch density 78.In one example, by for the first arc section 70 and the second arc section 74 institute of sewing The high level of detail (that is, high stitch definition) needing, therefore for this two section specified value stitch density 78.In other In embodiment, due to for first straight line section 68 of sewing, second straight line section 72 and low needed for the 3rd straight sections 76 Level of detail (that is, relatively low stitch definition), therefore specifies the stitch density 80 of change, this makes for these three straight sections Can be (that is, only to pass through with pattern remainder identical sewing speed these parts of sewing in the case that output is bigger Adjust the stitch quantity of sewing in predetermined distance, the pin number of such as per inch).

Can determine that the first arc section 70 and the second arc section 74 are not suitable for and/or meet for specifying the pin changing The threshold requirement of pin density 80.First and second arc sections 70 and 74 show compact circle or oval bent in the diagram Rate.In order to keep enough curvature details of the first and second arc sections 70 and 74, example during the sewing of sewing pattern 64 As stitch density that is preferred and/or needing bigger stitch concentration degree or higher.Higher stitch density remains arc section 70 and 74 more details, and create smooth, completely curvature.If using standard stitch density, first and second The curvature of arc section 70 and 74 may be less smooth, and this is possibly undesirable in final sewing pattern.Generally, more High per inch sews pin number (such as SPI) corresponding to the higher levels of fine detail that can retain in sewing pattern. Therefore, it may be determined that using, there is ratio for the element (being for example characterized as the element of straight line) needing less or least amount of detail The stitch density (such as " hydridization stitch ") of the change of the less SPI of standard stitch density.Using having ratio standard stitch density The stitch density of the change of less SPI may further result in faster sewing velocity, because being sewed using less SPI one Or multiple it is determined to be the element with less details.

With reference now to Fig. 5, according to embodiments of the invention, using variable stitch density along axis 114 sewing example The pattern 82 of property.In the 5 embodiment of figure 5, sewing pattern 84 includes multiple different elements for sewing with variable density. So, sewing pattern 84 is included with the first straight line section 86 of standard stitch density 88 sewing and is stitched with the stitch density 92 changing The second straight line section 90 threaded.Show the stitch density 92 being suitable for changing of sewing pattern 84 with relatively low stitch density Each several part, and it is shown suitable for each several part of standard stitch density 88 with higher stitch density.

As shown in figure 5, embodiments of the invention include determining whether the part of the element-specific of pattern 82 meets and be used for making The threshold value of the stitch density sewing with adjusting.In one embodiment, for the threshold value bag using the stitch density sewing adjusting Include, determine whether the part of pattern element meets threshold value sewing distance.According on one side, threshold value sewing distance can be between half Between inch and three inches.In another embodiment, at least one inch of the length of threshold value sewing distance.So, according to this Bright embodiment, when determine analyzed straight sections part be less than one inch threshold value sewing apart from when, this line part The stitch density sewing partly may being not suitable for using regulation of section.It should be noted that sewing distance included here is only It is example, is not construed as restricted, need because each sewing pattern is potentially based on the element of each sewing pattern The threshold value sewing distance of different determinations.And, it will be appreciated by persons skilled in the art that according to application and pattern, in millimeter extremely Threshold value sewing distance on the foot order of magnitude all should be considered in embodiment considered here.For example, for sewing landing The threshold value that umbrella limited or determined sews distance may be with the threshold value seam that pillowcase limited or determined for sewing on the order of magnitude Distance of threading is different.

In one embodiment, due to the length of the sewing pattern in the part 94 of Fig. 5, for the whole seam in this part 94 Thread pattern 82 specified value stitch density 88, and the single straight sections (such as 93,95 and 97) in this part 94 are all unsatisfactory for For the threshold length using stitch density 92 sewing changing.Similarly, according to embodiments of the invention, when arc section (distance of the second point for example on first point arc section to arc section, wherein, along arc in length for part This distance of the curvature measurement of section) less than one inch when, this arc section partly may be not suitable for using adjust stitch Density is sewed.So, as shown in figure 5, when each turning section 96 of sewing pattern 84 is less than one inch of threshold length, permissible Each turning section 96 with standard stitch density 88 this sewing pattern 84 of sewing.For example, " zig zag " in sewing pattern 84 can Threshold length can be unsatisfactory for, and the standard stitch density specified can be kept, thus maintaining this " zig zag " pattern part On sewing details integrality.

In an embodiment, once meeting the threshold value for minimum sewing distance, then each element of analysis sewing pattern is each Part, to determine whether this pattern and/or pattern part meet the threshold angle with respect to axis 114.In one embodiment, After having met threshold length, the threshold angle of a part for sewing pattern can be equal to or less than specific or restriction Threshold angle, such as be in 40 degree or less of angle with axis 114, to be suitable for the stitch density changing.Typically can pass through Element portions at least partially define threshold angle with respect to the orientation of axis 114, regardless of whether this axis is towards which direction (such as x-axis or y-axis), no matter also for the pattern with regard to axis of sewing, if with respect to horizontal or vertical axle Line is measuring this threshold angle.In other words, the every side in axis 114 there is the sewing pattern part of angle within 40 degree can To meet the threshold value using the stitch density sewing changing.In this context it is noted that for the horizontally and vertically axle being previously mentioned Line, they are descriptive with respect to pattern in itself, and do not mean that the vertical motion of such as needle.

Embodiments of the invention can also include determining whether a part for the element-specific of pattern meets for using tune The threshold value of the stitch density sewing of section.For example, in certain embodiments, in addition to determining and meeting threshold length, arc section Respective increment may each meet a threshold angle with respect to axis so that be designated with change stitch density.In figure In the exemplary patterns 98 of 6A, the method for variable stitch density of sewing includes multiple discernible pattern units that determine and sew Element.Fig. 6 A includes arc section sewing pattern 100, and it has some, for example, sewed (for example with standard stitch density 104 Be determined to be using preferred stitch density and/or specify stitch density sewing) Part I 102 and the stitch changing Density 108 is sewed the Part II 106 of (being for example determined to be the stitch density having preferred stitch density and/or specifying). In an embodiment, the threshold angle partly may being unsatisfactory for respect to axis 114 in Part I 102 for the sewing pattern 100. Therefore, in this case, even the Part I 102 in arc section may meet for using the stitch density changing It is also possible to discomfort is combined into Part I 102 specifies the stitch density 108 changing in the case of the threshold length of 108 sewing.In reality Apply in example, in all parts of sewing pattern 100, stitch density can change over the second stitch density from the first stitch density (and returning to the first stitch density).For example, point 110 at, when sewing clockwise with respect to axis 114, sewing pattern 100 from Standard stitch density 104 is changing into the stitch density 108 (such as " hydridization stitch " density) of change.Continuing sewing pattern 98 When, stitch density can be changing into standard stitch density 104 from the stitch density 108 changing at point 112 again.In embodiment In, variable density in pattern 98 can be depending on sewing pattern 100 when from being unsatisfactory for the threshold angle with respect to axis 114 Degree changes over the threshold angle (for example at point 110) meeting with respect to axis 114.In addition, in an embodiment, identical is sewed Pattern 100 from meet change over respect to the threshold angle of axis 114 be unsatisfactory for respect to axis 114 threshold angle (for example At point 110).So, single arc section can include some differing, and each of the plurality of part is corresponding In one or more different stitch density.

Referring now to Fig. 6 B, according to embodiments of the invention, the exemplary diagram of Fig. 6 A that sewed using variable stitch density The amplifier section 116 of case 98, the stitch density 108 including the Part I 102 sewed with standard stitch density 104 with to change The Part II 106 of sewing.In an embodiment, along amplifier section 116 arc section produce multiple increments, including increment A, B, C and D.Therefore, the arc section of interpolation (interpolated) can be to have the multiple increasings being compared with regard to axis 114 Any arc section of amount.The arc section of the interpolation of Fig. 6 B defines the increment being equal or approximately equal, in order to determine this arc Whether at least a portion of shape section meets the threshold angle with respect to axis 114, and wherein, a part can include one or many Individual increment.In an embodiment, the arc section of sewing pattern 100 can be interpolated to including multiple increment A, B, C and D, wherein, Each increment A, B, C and D approximately uniformly can be spaced apart with angle 126 with respect to arc axis 128.So, when with side clockwise During formula sewing, increment A can have in the increment starting point at point 118 and the increment terminal at point 120.Similarly, increment B can To have in the increment starting point at point 120 and the increment terminal at point 110；The increment that increment C can have at point 110 rises Point and the increment terminal at point 122；Increment D can have whole in the increment starting point at point 122 and the increment at point 124 Point.In the example of 6 b it, can be along the arc section of each incremental evaluation sewing pattern 100 of arc section, such as by increasing Amount A, B, C and D are limited.In another example, increment A, B, C and/or D can wholly or partly combine, to carry A part for arc section.During the analysis of sewing pattern 100, have multiple increments arc section a part of permissible It is compared with axis 114.In some embodiments of the invention, a part also referring to sewing pattern with another increment Neighbouring and/or adjacent increment.Usually it is appreciated that neighbouring and/or adjacent increment can form at least one of pattern The part of continuous sewing.

Therefore, below with reference to Fig. 6 C, the amplifier section 130 of the exemplary patterns 98 of Fig. 6 A describes, in sewing pattern 98 Inclusion one or more elements each several part when, determine using which kind of stitch density embodiment.Especially, the enforcement of Fig. 6 C Example describes the stitch density that the increment of the interpolation using Fig. 6 B determines whether using changing and sews arc section A part.In other embodiments, determine a little part between 118 and 110 meet threshold length and/or threshold value sewing away from From afterwards, determine, using the x-axis of positioning and y-axis at point 118, the angle that increment A is with respect to axis 114.In other words, Using the straight line 132 drawn between point 118 and point 120, determine increment with respect to axis 114 (parallel with y-axis at point 118) The angle 134 of A.In one embodiment, determine whether the first increment A meets the threshold angle with respect to axis 114.In Fig. 6 C Embodiment in, increment A is positioned with the angle bigger than threshold quantity with respect to axis 114, and is therefore designated with standard stitch Density.

Turning now to Fig. 6 D, the amplifier section 136 of the exemplary patterns 98 of Fig. 6 A further describes determination and is used for sewing Stitch density embodiment.For increment B, it is possible to use at point 120, with y-axis, the x-axis of positioning determine that increment B is relative Angle 140 in axis 114.In other words, using the straight line 138 drawn between point 120 and 110, can be with respect to axis 114 (being expressed as parallel with y-axis at point 120) determines the angle 140 of increment B.In one embodiment, based on the angle to increment A The assessment of the angle 140 of degree 134 and increment B, when angle 134 and angle 140 meet the threshold angle with respect to axis 114, Can determine whether the whole part of a little arc section between 118 and 110 meets the threshold angle with respect to axis 114.? In the embodiment of Fig. 6 D, increment B can be positioned with the angle bigger than threshold quantity with respect to axis 114, and therefore can be for increasing Amount B specified value stitch density.

It is likewise possible to determine the angle that increment C and D is with respect to axis 114 respectively, and determined specified using this angle Standard stitch density or the stitch density of change.In an embodiment, once it is determined that two of arc section neighbouring and/or adjacent Increment meet with respect to axis 114 specific threshold angle, then when can meet further combination increment threshold length When (with reference to Fig. 6 B), the stitch density of change can be specified for this two increments.Correspondingly, in the example of Fig. 6 C-6D, due to , more than the threshold angle angle value with respect to y-axis (that is, with respect to axis 114), therefore arbitrary increment is all for angle 134 and angle 140 The stitch density to change cannot be designated.So, in the embodiment of Fig. 6 C-6D, increment A and B be described as by Specify the standard stitch density for sewing.In certain embodiments, can be all parts specified value of sewing pattern Stitch density, for example, " give tacit consent to " stitch density specified.Therefore, in an embodiment, only figuratum meet whole two and can fit Threshold value just may adapt to using the pin changing with regard to those parts of threshold angle and threshold value sewing distance Pin density (for example lower than the existing of pattern and/or standard stitch density stitch density) sewing.In one embodiment, phase Threshold angle for axis 114 is 40 degree or less.
